This nav/comm also includes matching tray, connectors, and headphone/mic jacks that are pre-wired. Hook this to 14 volt power, ground, and antenna and start flying! This would be a simple DIY project to get your experimental or other homebuilt setup for communication without a costly avionics shop installation. Otherwise, mount in your vehicle or garage and use the built-in speaker to listen to air traffic at your leisure. Black plastic housing for use as a ground unit can be included at buyer's request. Need an antenna? I can work out a package deal to include one as well. FREE shipping via USPS priority mail in the continental US. International buyers, please inquire for shipping quote.
